Parking is free, next door, however, we ended up taking the Metra to Union Station then a cab to the venue. Only thing was it would've been nice to know that the Metra ran every two hours on Sunday and we missed the 8:40 train so we had to wait two hours for the next train! If we had known, we probably would've left the venue a few minutes early! Please note that this was in NO WAY the fault of the venue. Just wanted other out-of-towners to know.
